Distribute index cards and markers. Set a topic, e.g. one of the following:
How did you feel during the iteration?
What was the most remarkable moment?
What was the biggest problem?
What did you long for?
If the last iteration had been a circus performance, what part did you play? Juggler, funambulist, clown, knife-thrower, ...
Ask the team members to draw their answer. Post all drawings on a whiteboard. For each drawing let people guess what it means, before the artist explains it. Metaphors open new viewpoints and create a shared understanding.

Do you suspect that unspoken taboos are holding back the team? Consider this silent activity: Stress confidentiality ('What happens in Vegas stays in Vegas') and announce that all notes of this activity will be destroyed in the end. Only afterwards hand out a piece of paper to each participant to write down the biggest unspoken taboo in the company. When everyone's done, they pass their paper to their left-hand neighbors. The neighbors read and may add comments. Papers are passed on and on until they return to their authors. One last read. Then all pages are ceremoniously shredded or (if you're outside) burned.
Prepare a flip chart with 3 columns titled 'What', 'Who', and 'Due'. Ask one participant after the other, what they want to do to advance the team. Write down the task, agree on a 'done by'-date and let them sign their name. If someone suggests an action for the whole team, the proposer needs to get buy-in (and signatures) from the others.
Prepare 3 flip chart papers titled 'Helped', 'Hindered', and 'Hypothesis' (suggestions for things to try out). Ask participants to help you grow and improve as a facilitator by writing you sticky notes and signing their initials so that you may ask questions later.
